to eectthe automat-ic `fillingl and weighing` l Referring to thedrawingvby'numeralgl,

designates a circular hollow base having bearings, 2, in diametricallyopposite sides which sustain a horizontal driving shaft, 3, having abeveled pinion, 4, thereon adjacent one end thereof. A horizontalbracket bearing, 5, (see Figs. 5 and 7 is secured against the verticalwall of the base and sustains a lower short horizontal shaft, 6, one endof which carries a bevel gear, 7, that meshes with and is driven by thepinion, 4, on the main shaft and the opposite end of which carries apinion, 8. The bracket bearing, 5, also sustains an upper horizontalshaft, 9, which mounts a gear, 10, that is driven by pinion, 8, directlybeneath it, and which also has a worm, 11, thereon that engages a rack,

Y- 12, on a circular ring-plate, 13, that depends from the bottom of atable or carrier, 14. This table or carrier, 14, extends horizontallyover the hollow base, 1, and has a circular depending circumferentialflange, 15, Vwhich carries a plurality of rollers, 16, that travel onthe upper rim edge, 17, of the base which serves as a track for thecarrier or table. Y It will thus be understood that the table or carrieris revolved by the worm, 11, and rack, 12, and that it is sustained onthe rim-edge of the base by the rollers, 16.

The table or carrier, 14, is provided` with a plurality of brackets, 18,which project above its upper surface and sustain scale beams, 19, theouter ends of which pivotall'y carry platform supports, 20. These supports, see Figs. 14,v 15 and 16 of the drawings, have circular bearingsor eyes, 21, which straddle the outer ends of and are pivotallyconnected to the scale beams and arealso provided'with horizontal andvertiside lugs, 30, which` perforations areinter-i vertically calportions, 22, and, 23, respectively. The vertlcal portions, 23, of thesupports have extending perforations, 24, through which a. rod, 25,extends which latter serves as a vertical guide for a lling Ynozzlemechanism as will presently appear.

Vertical lugs or flanges, 26,arel provided at opposite edges of thevertical portion of the support which flanges project slightly tothesides and serve as guides for the upright channel'portion,l 27, ofscale platforms, 28, as clearly seen in- Figs. 17, 18 and 19 ofthedrawings. Plates, 29, are attached to the iiiner sides of the channelportion, 27, of the scale platform and extend vertically at the rearofthe flanges, 26, whereby to prevent Y lateral separation of theplatform from the vertical portion, 2 3, of the support but which permitthe'platform to. bemoved vertically for adjustment with respect to saidsupport. The upper end of the channel portion, 27,

nally threaded so as t'o receive and engage the lower ends of verticaladjusting screws, 31. These screws extend vertically abovethe .Y lugs,30,'and their upper ends pass freely @catia through side lugs, 32, onthe vertical portion, Y23, of the supports, 29, and at the npper side ofsaid latter lugs5 32, the screws carry small wheels, 33, by means ofwhich platforms may be raised or lowered with s respect to the iillingnozzles presently to be described, to accommodate bags of differentlengths.

By reference to Figs. 1, 3,4 and 17 it will be seen that the scaleplatforms are provided with slots, 34, forming central vertical slotstherein, and that at each side of the slot each platform is providedwith downwardly-extending brackets, 35, the lower ends of which areslightly separated. A bell-crank lever, 36, is pivotally sustainedbetween the lower ends of the platform brackets, 35, and-the lower armof said lever carries a roller,A 37, while Athe upper arm thereofpivotally connects a bar, 38,'V which extends upwardly in a slightlyinclined direction and passes from the slot, 34, from the under to theupper side of the platform. This bar, 38, carries a s curved bag-ejectorplate, 39, which extends or projects vertically above the platform, 28,and has position between the upright channel portion, 27, and the baglthat is undergoing'the hlling operation. When the bag has been lledand'has been conveyed to the point of ejection, the roller, 37, onbell-crank lever will contact with a suitable stationary cam or track,40, and the bell crank thereby swung down and outwardly so as to draw.the ejector plate, 39, outward over the platform and thus push thefilled bag from Said platform.

A column or tubular support, 41, has its lower end seated upon the uppersurface of the table or carrier, 14, and has a slightly reduced upperend which is embraced by a f collar, 42, which carriesupwardly-projectingbracket arms, 43, (see Figy20) that sustain acentralupper bea-ring, 44. This bearing receives the upper end of a shaft, 45,that extends vertically through the colunen and which has its lower endsseated in a step bearing, 46, that rests upon a stationary sup-port, 47,that extends hori-V zontally andY diametrically across the interior ofthe circular base, 1, as clearly seen` in Fig.v 5. The lower end of thisshaft, 45, is

Valso embraced by a sleeve, 48, that extends slightly into the lower endof the column, 41, and which is carried on the ring-plate,

las

shown in Fig. Between the sleeve, 48,

and the hearing, 46,i the shaft, 45, car'- zries a bevel pinion, 49,which'rneshes and is driven by a bevel gear, 50, on the main -long asthe driving shaft, 3, is revolved and also that the table, 14; column,41; scale platforms and bag ejectors are also made to travel `in acircular direction with respect'to. t-he base, 1. It will further beseen that the bearing, 44, vat the upper end of the column also revolveswith the column.

The collar, 42, at lthe upper endof the column carries a pluralityofbrackets, 52, having downwardly-inclined extensions, 53, which formsupports for conveyer trunks, 54. Inthe present instance these trunks,of which there are four in number, have an inclined position with atubular extension, 55, at the lower end and a bearing plate, 56, at theupper end.` lAplunger-lik'e stem, 57, v'snugly its the tubularextension, 55, and has a cen- I tral socketl which receives the lowerend of a shaft, 58, while the upperend of said shaft passes through thebearing plate, 56, and enters an inclined socket', 59, in the centralupper bearing, 44, -as seen inFig. 2, of the f y drawings. AThe shaft,58, is provided with a` screw or conveyer, 60, which revolves in thetrunk,.54, and the upper end of said shaft.

carries a beveled friction pulley, 61, which contacts with and is drivenby a .large friction Wheel, 62, on the upper end of the ver# ticalshaft, 45.

Casin'gs or covers, 63, are seated on the upper sides'of the conveyertrunks, 54, and

. carry a housing, 64, that completely incloses l projects up into theshell, leaving an annular the upper end oft'he machine and said hous'--ing adjustably sustains a circularpshell, 66,

by means of vertically-slotted bars, 66, and

`wingbolts, 66h.' The shell, 66, depends cen'7 trally over the c ap'plate and receives the lower end of a chute, 67, through which thevmaterial tobe weighed and bagged is fed to the interior of the housing.Aconical cap plate,- 65,1covers the upper bearing, 44, and

passage through which the materials pass.

It lwill be understood that the covers, 63, housing, 64, cap-plate, 65,and circular shell,

166, all revolve withthe tubular support, 41, from which they areindirectly sustained ,but that the, Chute, 67, that depends from asuitable eonveyer, 68, over the machine does not revolve, but merelydirects the materials into the housin wherein it will be distributedbythe conica' cap plate into the several conveyer trunks. w

The lower end of each conveyer trunk carries a .depending tube, 69,which forms a discharge nozzle for the escape of the material into thebag which will presently be explained.

The rod, 25, which extends vertlcally adjacent to the bag support, 20,isconnected at its upper end tothe outery end of a pivoted "the latter-settles lbecause of theweight of the material in the bag-the rod willmove downv wardly therewith and'when the weight is re- .moved the ilatform and rod will moveupwardly. T is downward movement of theplatform and rod is utilized to elect a closure of thel lower 'end ofthe filling tubes as the weighted bagoperates the scale platl formsandalso operates the' mechanism that releasesthe filled bag from the endof the iilling tube, as will,` now be described, reference being made.particularly to Figs. l, 2, 8, 9, 10 and 11 ofthe drawings.

By reference to Figs. l and 2, .it will be noted that a tubular support,72, is carried on the vertical rod, 25. This support is sustainedr byalcounter-ba'lance weight, 73, that around a roller, 7 5", at the upperend of the rod,.-tl1'e-weight being suiiicient to `balance the supportand the,device carried thereby.

A bracket, 76, extends horizontally from the support and carries a heador sleeve 77, at its outer end which encircles the discharge nozzle, 69,and is movable vertically there-` on. This head'orsleeve is provided atdia.-

metrically opposite sides with lugs, 78,'v

which pivotally sustain bag-engaging arms', 79, each having a lever-end,80,-that is rigld therewith and which extends at right angles thereto asseen Iclearly in Figs. 107Aand 41-1. The bag-engaging arms, 79,normally, and during theabsence'of Aa bag, extend down'- Vwardly fromthe lugs,.78, while thev leverends, 80, thereof at that time projecthorizontally. l"These positionsof the arms andV lever-ends enable themouth opening, 81,. of the bag, 82, to be readily passed upwardly,around the Vlower end of the nozzle; and ,head

depends from a band, 74, which passes A or sleeve andwhile doing thisthe hands of.`

the operator may be directed against-the vunder sideof the leverends andturn said ends l n upwardly 4against the. head and by such '115 movementthrow the arms, 79, horizontally,

as shown in Fig. 11, so they will project laterally at the inner side ofthe -fillingopening of the 'bag Aand sustain the latter. Theoperatorthen raises the 'head or sleeve, 77,

by sliding the'same on the tube, 69, which also elevates bracket,76, andhead, 7 2, .all of which are counter-balanced n by weight, 73.- When thehead or sleeve is'raised 'on the lill- 'ingtube to the position shown atthe right hand side of Figs. 1 and 2 an arm, 83, that projects outwardlyfrom a lever, 84, 'will alsobe raised and the said lever will be swungso that itslower end, 85, will assume la substantially verticalposition. A

By reference to said Figs.- 1, 2, 8 and 9 it i 440 that projects at theunder sideof the bracket will be seen that the bracket, 76, is providedY with a central vertical opening or slot, 86,

through which the lower end, 85, of the lever, 84, projects and in whichsaid lever-end may swing. It will also be seen by reference to Figs. 8and 9 that the upper horizontal surface of the bracket, 76, carries twoY clamping levers, 87, which are pivoted thereon at the rear of the'head or sleeve, 77. These clampinglevers, 87, are provided with jaws,88, at their outer endswhich projectA forward and at opposite sides ofthe head or sleeve, 77, and are so positioned that they maybe movedtoward said head and by engaging the lever-ends, 80, of the bag-holderkeep said ends pressed against the head and hold the arms', 7 9,horizontally during the filling operation. The inner ends of theclamping levers, 87, carry toggle levers, 89, which latter, at the pointwhere they pivotally connect the clamping levers, are provided withoutwardly-projecting latch lugs,-

90, 'which are rigid therewith, and-against which fiat leaf springs, 91,press to normally keep the toggle broken and the jaws, 88, projectedoutwardly away from the' head. When however, the head, 77, and bracket,76, 'are raised, and the lever, 84, .is swung outwardly by raising arm,83, the broad fiat head, 92, of lever, 84, Vwill move outwardly throughthe slot, 86, of the bracket and will contact with the centralv pivotedportions, 93, of the clamping levers at the rear of the pivot and causethe jaws, 88, to move towardthe head, 77, and hold the lever-ends, 80,in the vertical position, thus retaining the filling end of the bagaround the nozzle or filling tube.

The lever, 84C, is pivoted to an arm, 94,

extensions, 53, below lthe lconveyer trunks and said lever has an arm,95, at its upper end which is pivotally connected by a link,

, 5., 9G, to the upper end 4of avertical rod, 97,

which extends all the way from the said link l down at the side of thecentral tubular Support, 41, and has its lower end, 98, project- Vingthrough perforations, 99, in the base of the support; the carriage, 14,and ring-plate, 13, as clearly seen in Fig; 3,'for a purpose presentlytobe explained. The upper end of the vertical rod-,97, is also pivotallyconnected to a yoke, 100, that'encircles the conveyer' trunk, 54, andwhich is pivotally sus'- tained by lugs, 101, at the upper side of thecasing or cover, 63, over the conveyer trunk.n

- This yoke has an arm, 102, that projects centrally overv thecover, 63,and 'which carries a depending rod, 103, that extends down through thecover 'and also` through the filling tube, 69, and has :icone-plug,V104, at its lower end to effect a closure of the discharge end ofthe'filling tube. Y

By reference to Fig. 1 it will be seen that "re yoke, 100, carries abar, .105, at'each side support.

99ans permits the conveyer shaft, 58 to move` downwardly a sufficientdistance ,to disengage the friction pulley, 61,.from the wheel, 62,thereby causing the shaft, to discontinue its revolution andconsequently the material in the conveyer trunk Awill no .longer beforced vbythe screw, 60, toward the lower end. Thus it will beunderstood that when a predetermined weight of material has beendischarged into the bag the Blling nozzle 4will be closed and the feedscrew will stop revolving. Toefi'ect this cuttingoff operationautomatically it will be Anoted that a hanger bracket, 106, is providedon the bottom of the conveyer-trunk and that an arm, 107, is pivotedthereto. This arm `is provided with screw-stops, 108, and, 109,respectively,-the latter having position directly over the upper end ofa weight rod, 110, which extends vertically at the'side'of the tubularsupport, lll, and whose lower end is pivot-ally connected with the scalebeams.

19, above the table or carrier. This' rod carries the weights, 111, and`its upper end is sustained loosely by means of a. link, 112, that ispivoted to the side of the tubular when the lever, s4,- and infact au.are au- ,ing mechanism is in the position to fill, the

screw stop, 108, on pivoted arm, 107, baspo'- sit-ion at the-joint ofthe link, 96, and arm, 95, of the lever, 84, as seen at the .right handside of Fig. 2 of the drawing so that when weight rod, 110, is elevatedby thefilled bag,Y its upper end will raise arm, 107, and move stop,108, outwardlyand thereby move the link,`96, and arm,'95, outwardlysuflielently to cause the -lower end, 85, of lever, 84, to swingrearwardly in the slot ofthe bracket, 76, and by such movement contactwith the toggle levers, 89, andY break their locking vjoint so that thesprings, 91, can operate the clamping jaws. 88. to release lever-ends,80,

and free the filled bag from the .nozzle or filling tube. j

.Asthe filling of the bag progresses itfwill 'graduallyv draw downV thehead or sleeve,

77. so that when completely filled the head will have position at thelower end of the filling tube.

During the operation of themachine it may sometimes occur that a bag isunfilled or not completely filled immediately before it reaches thepoint of discharge, and weA have therefore provided means whereby therotation of the machine may be stopped long enough to permitthe bag tobe filled before discharging it. This is effected by means of deviceswhich will non1 be described reference beinfrmade articularl to Figs. 2,3,4 5 and 6.

It is to be understood that during the lling of the bag, see righthand'side of Figs. 2 and 3, the inner end of the scale beam, 19, will bedepressed and said end of `the scale beam is'provided with adependingpost, 113, which rises and falls with the scale beam andv which alsotravels in a circuit as the table revolves.

The horizontal support, 47, in the circular b ase pivotal'ly sustains anarched or curved bracket, 114,- the upper part of whichpivotallyconn'eets with the rear end of a horizontal`clutch pla-te, 115,so that the clutch plate andthe curved bracket may swing together. Theouter end of this clutch plate is connected to the-upper end of ayoke,

116, the lower end of .which is `p'ivotally se-- cured at the bottom tothe base and which `extends through Yand Uengages a Icircular .clutchmember, 119, that 'is maintained groove in a clutchmember, 117, thatrevolves with the main driving shaft, 3. This grooved clutch member ismounted on the main shaft by a connection, such as a spline,

so as to permit it to be moved longitudinally l on'the shaft,-a spring,1,18, at the inner side of the clutch member, 117, serves to normallypresssaid member outwardly on the shaft and into engagement with anotherloosely on the shaft and which has no longitudinal vmovement thereon.Byreferring to Figs. 5 and 6, it will be'seen that a short verticalsupport, 120, is carried on the upper side,` of the horizontal support,47, and

that ahorizontal lever, 121, is pivotally sustained between its ends bysaid support. One end of this lever projects at the outer side of thepivoted bracket, 114, while the other end thereof, 122, curvesbackwardly v so as to lie in the path of the lower end of any post, 113,that is in the depressed posi'- t1on as it approaches said lever end,122.

If a-lpost, 113, is depressed, which it will be A if .the weight in thebag 'is' insuiicient to raise the inner end of the scale beam, 19, saiddepressed post .will contact with the end, 122, of said lever and swingsaid lever end in the direction in which the post is traveling.Consequently the other end of the Alever will be moved in the opposite'direction and throw the pivoted bracket, 114,

and clutch plate toward the large,v gear, 5 0,

and thereby move the clutch member, .117, against the action of thespring, 118, and out Aof engagement with the clutch member, 119. Thisoperation will permit the clutch member, 119, to cease revolving andconsequently pinion, 4,*and gears, 7, 8, and, 10,v

will become idle and the table, 14, will come to rest, and while the'filling of the bags will continue they will not advance. This conditionwill remain until the foremost'v bag will become heavy enough to raisescale y beam, 19, whereupon post, 113',`will rise above lever end, 122,and the spring, 118,

will then move all the affected parts to their normal operative positionto cause the clutch members to again engage. and rotate the table.

If for' any reason the operator fails to 4other end of said groove.Theiinner end of 'this diagonal groove (see Fig. 5) is normally inthedirect circular path of the lower ends, 98, of the rods, 97, which rodsi are depressed when heads'or sleeves, 77 on the filling tubes arelowered, consequently if a b ag is absent, as it is wlien the head orsleeve, 77, is in the lowered position, the end, 98,` of rod, 97, willbe depressed where it will enter one endbf the diagonal groove,

123, and as l.the rod cannot move laterallyv it will force theclutchplate, 115, inwardly as it passes through thengroove and this movementof the clutch plate will operate the clutch member, 117, to stop themachine until the rod, 97, is'elevated by the attachment of a bag andthe elevation of the head, 77, and forward movement of lever, 84.

In the operation of the machine the. table,

scale platformsand. filling conveyer trunks 'all turn together. Theoperator will place his hands in the open ends of bag 'and draw it uparound the `nozzle,69,.and also around the lower end ofthe movable head,77 and depending bag-engaging arms, 79, thereon. In doing/this the handswillV be brought against the under side of. the lever ends, 80, .whichat that time extend horizon- Ltally and said ends .will bevturned,upwardly and against the circumference of the head,

7 7 thereby throwing the arms, 79, outwardly to engage the bag, as seenin Figs. 10 and 11.

The operator then raises' 'the head, 77 on thetube, 69, which alsoelevates bracket, 76,

and head, 72, and clamping jaws, 88, will engage lever-ends, 80, andhold, the bag-engaging arms, 79,' in the operated position and the bag'open to recelve" the materia-l from the nozzle. lSimultaneously with'thev elevation of the head, A7 7 to efect a clamping of the bag thefarm, 83, will be elevated and the upper end, 95, of lever, 84, w1llactuate bag olf, where it will be received on will do two things,-1st,lower rod, 103, and move cone-plug, 104, from the lower end of nozzle,69, thus allowing the material to discharge into the bag and, second,draw bars, 105, upwardly to impart a like movement to conveyer shaft,58, and thereby' engage friction pulley, 61, with wheels, 62, and feedthe material through the trunk to the nozzle, 69, and discharge it intothe bag. This condition prevails until the` bag has received therequired weight of material.

Y It will be understood that while the bag is bein filled its lower endrests upon a scale pi scale beam, 19, and a weighted rod, 110. Whentherefore the weight in the bag is suilcient to actuate the beam, 19,the rod', 110, and weights, 111, thereon will be elevated,- the upperend of said rod, 110, will raise carrying arm, 107, with it, The stop,108, will thus press link, 96, and lever end, 95, outwardly which willrock yoke, 100, and raise rod, 103, to close the discharge nozzle bydrawing cone plug, 104, up against the lower end thereof. At this same.time the lower end, 85, of lever, 8-1, will swing rearwardly in the slotof bracket, 76, and will break the toggle joint and allow springs, 91,to move the clam ing jaws, 88, and thus release the lever en s, 80, tofre the openend of the lled bag. A

v When the filled bag has been released fromv about the lling nozzle andis conveyed around to the point where it is to be dis- 'charged theroller, 37, will cont-act' with cam or track, 40, which will swing theupper end of lever, 36, outwardly and also move the bar, 38and ejectorplate, 39, in the same direction, as shown at ,the lefthand side ofFig.' 1, and thus push the filled able conveyer to carry it olf.

If for any reason a bag remains unilled when it reaches the point ofdischarge We have provided means for stopping the rotation of themachine until the bag receives the desired quantity of material. This iselfected by means ofthe depending post, 113, at the inner end of thescale beam, 19, which post, when the weight of the bag is insultic1entto raise the inner end of the 'scale beam will depend further than whenthe said end of the scale beam is raised because the post rises andfalls with the scale beam. When therefore, the bag approaches the pointof discharge and. is insuiiciently filled t-he post, 113, and inner endof scale beam, 19, will both be in a depressed position and the lowerend of the post will contact with the end, 122, of lever, 121, and swingthe lever s in a horizontal plane which will operate to tform', 28,which is sustained by a` a suitthe bag to continue. When the`bagreceives the desired quantity of material Vthe scale beam will' rockand draw the post, 113, upwardly thus-releasing lever, 121, and spring,118, will force the clutch members, 117, and, 119, into engagement toagain impart a rotary motion to 4the table and scale plat-forms.

In the operation ofthe machine provision is also made for stoppingthe'revolution of the machine in case the operator fails to attach anempty bag to a filling tube upon removing a filled bag. When a filledbag is removed from the head,77, the latter is in a depressed positionand the position of lever, 84, is such that its uppe1';end,. 95, whichis connected by link, 96, with the upper end of vertical rod, 97, thatsaid rod will be depressed. The lower end, 98,l of this rod Aits uppersurface which is so' arranged that when a depressed end, 98, of ay rod,97, enters said groove it will cause the clutch plate, 115, to be movedhorizontally toward the gear, 50, and thus actuate'the clutch member,117, to withdraw it from member,r119, thereby stopping further rotationuntil a bag has been placed on the empty holder and the rod, 97, raisedso its lower end, 98, will be withdrawn from the groove, 123.

It will thus be understood that if a bag is not'placed on Aa lillingtube to be filled, or if a bag is not sufficiently lilled when itreaches the point for its discharge themachine will be 'stopped untileither of these things are corrected.
